微信小程序获取用户手机号

获取手机号第一次不能在开发工具中使用，需要在真机上获取，第一次需要用户获取短信验证码。

微信小程序代码：

getPhoneNumber: function (e) {

if (e.detail.errMsg == 'getPhoneNumber:fail user deny') {

that.callBackError(e.detail.errMsg);

} else {

let params = {

open_id: wx.getStorageSync('wx_openid'),//用户open_id,不一定需要

sessionKey: wx.getStorageSync('session_key'),//调用wx.loign接口 获取code 上传服务器获取用户open_id ,session_key

encryptedData: e.detail.encryptedData,//调用获取用户手机号组件，直接获取

iv: e.detail.iv,//调用获取用户手机号组件，直接获取

userType: 3//不一定需要

}

console.log(params);

return;

https.user(config.user, params).then((res) => {

console.log(res)

}).catch(e => {

that.callBackError(e.message);

});

}

},

 

thinkPHP5代码

use applibwxlibwxBizDataCrypt;

private function getUserPhone($user)
{
    $appid = Config::get("WXAPPID");
    $sessionKey = $_POST['sessionKey'];
    $encryptedData = $_POST['encryptedData'];
    $iv = $_POST['iv'];
    $wx = new wxBizDataCrypt($appid, $sessionKey);//微信解密函数，微信提供了php代码dome
    $errCode = $wx->decryptData($encryptedData, $iv, $data);//微信解密函数
    if ($errCode == 0) {
        $data = json_decode($data, ture);
        $phoneNumber = $data['phoneNumber'];
        $user->where('open_id',$_POST['wx_openid'])->update(['phone' => $phoneNumber]);
        return json_encode(['errorCode' => 0,"phone" => $phoneNumber]);
    } else {
        return $data;
    }
}
